Young Ray, I am very sorry to hear that you’re going blind. However, that’s no reason that you can’t play wonderful music and be happy for the rest of your life. I have a couple options for you.
A) The Trumpet. This has three buttons on it.
B) The Piano. This has more buttons than a human could ever hope to count.
Anyway, I’m sure your heart will guide you towards the right instrument for a blind man, either the instrument that you can hold all of in your hand or the one that is more complicated than your average 4-cylinder automobile.
